Privacy policy
The Voltz Mail and Calendar Connector (“the connector”) is a private tool run by Voltz Software. It lets Claude, the AI assistant made by Anthropic, search and read email, create drafts, and read calendars in accounts their owner has connected. When the owner allows it for a particular Claude app, it can also send email, organize mail (archive, move to Trash, mark read or unread), and create, change or cancel calendar events. It isn't offered to the public: only Voltz Software's own accounts are connected, and only Voltz Software can use it.
What it accesses
- Gmail: messages and their metadata, to search and read them (
gmail.readonly), and creating drafts and, where the owner allows it, sending messages (gmail.compose), and, where the owner allows it, archiving, moving to Trash and marking read or unread (gmail.modify). It never deletes messages permanently. - Google Calendar: calendars and events, to read them (
calendar.readonly), and, where the owner allows it, to create events and change or cancel the ones the connector created (calendar.events). - Google account identity: the account's email address (
openid,userinfo.email), to know which account was connected. - iCloud: mail over IMAP (reading, drafts, and organizing where allowed) and SMTP (sending, where allowed), and calendars over CalDAV, with an app-specific password.
How it uses that data
Only to carry out a request the account owner makes through Claude, such as finding an email, listing tomorrow's events, or sending a reply. Results go back to the Claude conversation that asked for them. Sending and calendar changes happen only for Claude apps the owner has allowed to, at most 25 messages per account per day. The connector doesn't use the data for advertising, doesn't sell it, and doesn't use it to develop, improve or train AI or machine-learning models.
What it stores
- For each connected Google account, an OAuth refresh token, encrypted with AES-256-GCM.
- The iCloud app-specific password, as an encrypted Cloudflare secret.
- A log of each request: the time, the tool used, which account, whether it worked and how long it took. It never includes message or event contents. Log entries are deleted after 90 days.
- For each message sent: the time, the account, the number of recipients, the subject and the message ID. Not the body and not the addresses. Deleted after 90 days.
- For each archive, trash or mark read/unread request: the time, the account, the action and how many messages it changed. Not which ones. Deleted after 90 days.
The connector doesn't keep copies of emails, attachments or calendar events. It fetches them when asked and passes them on. It runs on Cloudflare Workers, and its data is stored with Cloudflare.
Who it's shared with
Data goes only to Anthropic's Claude, in the conversation where the owner asked for it, and to Cloudflare, which hosts the connector. Nobody else receives it, and no person reads it, unless the owner asks or the law requires it.
Google API Services User Data Policy
The connector's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
Removing access
Disconnecting an account deletes its stored token. Google access can also be revoked at any time at myaccount.google.com/permissions, and iCloud access by revoking the app-specific password at account.apple.com.
